Assume that any mean difference is significant. Describe the effects for the table below:   B1 B2 A1 18 16 A2 22 20

A researcher reports t(12) = 2.86, p < .05 for a repeated-measures research study.  How many individuals participated in the study?

A graduate student is conducting a research study to determine if 3 different brands of pre-workout supplements affect the rate of muscle growth. In each treatment, the researcher uses a sample of n = 10 people in each treatment. What is N?

For an experiment involving 2 levels of factor A and 3 levels of factor B with a sample of 5 in each treatment condition, what is the value for dfwithin?

An analysis of variances produces dfbetween = 3 and dfwithin = 24.  If each treatment has the same number of participants, then how many participants are in each treatment?

For a perfectly symmetrical distribution with µ = 30, what is the most probable value for the mode?

Using z-scores, a population with µ = 37 and σ = 6 is standardized so that the new mean is µ = 50 and σ = 10.  After the standardization, one individual has a score of X = 55.  What was this individual’s score in the original distribution?

If other factors are held constant, which of the following sets of data is most likely to produce a significant value for the repeated-measures t statistic?

The relationship between a statistic and a parameter is the same as the relationship between ____.

What is the value of SS for the following set of scores?  Scores: 0, 1, 4, 5
